DNG (Digital Native) is a lossless raw image file format developed by Adobe Systems in 2004 for digital photography. Generally, DNG is structurally similar to TIFF format and is a royalty-free format. This means that anyone can use DNG format as per Adobe’s published license. Also, DNG uses lossless data compression and is compatible with all Adobe products.
TIFF (Tagged Image File Format) is a standard computer image file format used for saving raster graphic images. It was first developed for desktop publishing by Aldus Corporation, which was later acquired by Adobe Systems in 1994. Interestingly, TIFFs can store information in lossless format and also supports the LZW compression algorithm for reducing the file size.
